CHEESE-PRESS.

Specification of Letters Patent No. 1,650, dated June 20, 1840.

To all whom t may concern.'

, Be it known that I, J. A. FLETCHER, of Irasbury, in the county of Orleans and State of Vermont, have invented an Improved Press for Pressing Cheese and other Articles, which I denominate the Pendulous Self-Acting Press and I do hereby declare that the following is a full and exact description thereof.

In my press the weight of the cheese or other substance to be pressed and the weight of the whole press act conjointly as the 'power by which the pressure is to be made, a circumstance which constitutes an essential difference between it andthose presses in which the weight of the substance pressed alone has been made the operating power, while at the same time my press is more simple in its construction and more readily managed than any other heretofore mad-e the construction of which has become known to me.

In the accompanying drawing, A, A, A, is the frame of my press, the lower part of which A, A', constitutes the bed, upon which the substance to be pressed is the rest.` B, is the follower, which is guided up and down by the side pieces of the frame.

C, C, are two levers, notched or forked, at their inner ends, so as to embrace the uprights or side pieces, andv to bear upon the followers. On the upper sides of the forked ends of these levers there are transverse notches, or flutes a, a., a, to adapt them to bear against the pins b, Z9, which pass through the uprights A, A, and constitute the fulcra of the levers C, C, which levers may consequently be shifted so as to increase or diminish their power.

it when it is desired to take the action off from the levers.

Instead of the simple transverse flutes across the forked ends of the levers, there may be loops, or rings affixed to them, as shown at c, c, or other analogous devices may be employed.

The press may be raised by means of a tackle, or other mechanical device, in modes known to every machinist.

I-Iaving thus fully described the manner in which I construct and arrange my pendulous self-acting, press, what I claim therein as constituting my invention, and desire to secure by Letters Patent, is-

The so forming and combining the respective parts, as herein described, that the whole press, with its load, shall be suspended by the longer arms of the levers C, C, and the shorter arms be thereby caused to act upon the follower substantially as set forth. v
